Yaxin-1165 Chl-Fluo Kinetics Measurement System is the 4th generation chlorophyII fluorescence instrument, based on Yaxin-1l6lG and Yaxin-1162. It has been upgraded from the inside to the outside. In terms of appearance, it has a colour touchable display, a humanized industrial design, and applies ABS environmental protection material. In terms of functionally, it is equipped with eight fixed measurement modes. Moreover, a custom mode for experienced users is provided for some experienced users, that can measure Q_A-reoxidation kinetics and S-state transitions. It truly enables" measure anything you want" in fluorescence kinetics. In terms of performance, over the last 10 years, our company has overcome the problem of weak signal instability in low light by improving the signal-to-noise ratio. It makes the weak signal experimental data more authentic and credible. In addition, to fully meet the needs of users, we have launched a two-color three-light configuration, as well as red and blue LED matched to the actinic light.
